Title: Improvements relating to the heat treatment of magnetizable metal
IPC: C21D11/00
Filed: 1930-09-02
Abstract: 360,552. Annealing. HEVI - DUTY ELECTRIC CO., 4100, Highland Boulevard, Milwaukee, Wisconsin, U.S.A.-(Assignees of Smalley, E. L. ; Whitefish Bay, Wisconsin, U.S.A.) Sept. 2, 1930, No. 26196. Convention date, Sept. 3, 1929. [Class 72.] In furnaces for magnetizable metal through which the metal is positively and intermittently fed either by a flexible conveyer or by a pusher acting upon the rearmost of successive charges a magnetic flux is passed through the metal by a primary coil during the heat treatment and the loss of magnetic properties occurring at the critical temperature is utilized to bring about automatic movement of the metal from the heat treatment position, the progress of the heating being indicated by a galvanometer in circuit with a secondary coil. As shown the charges 1 are moved through the furnace chamber 3 on a conveyer 2 driven by an electric motor 4 and are adapted to be aligned with opposite pole members 6, 7 of a magnetic circuit 5. A primary winding 30 on the polepiece 7 energized from a line 31 establishes a field through the furnace chamber and until the critical temperature is reached the flux energizes a secondary coil 11 on the polepiece 6 connected to a solenoid 10 which opens the circuit of the motor 4 at 8. When the flux decreases due to change in the magnetic properties of the charge the switch 8 is closed starting the conveyer 2 to move the charge 1 out of the furnace or to a position for further heat treatment, the next charge 12 taking its place. The circuits are balanced preparatory to heating by a variable reactance 25 and a galvanometer 19, Fig. 3, having its moving coil 23 connected in series with the variable reactance, the secondary coil 24 and the solenoid 10 while its field winding 20 is connected across the supply line 21 for the primary coil 22. When the charge is introduced the reactance 25 is adjusted to obtain a predetermined balanced position of the galvanometer pointer and movement from this position advises the operator of the progress of the heating.

Abstract: 984,745. Fuel injection pumps. C.A.V. Ltd. June 25, 1963 [July 11, 1962], No. 26624/62. Heading F1A. [Also in Division G3] In a fuel injection pump having a rotary distributer, two plungers 8 extend transversely to the distributer and are acted upon by an annular cam 10, the angular setting of which is varied by a fluid operated piston 22. A passage 32 is connected to the pump outlet and pressurised fuel passes into the interior of a bore 24 in the piston 22 via a passage 31. The fuel flows through a restricted groove 29 in a spring loaded valve member 25 and, when a pre-determined pressure is exceeded, moves the member 25 so as to bring a passage 30 into communication with the passage 31. Pressurised fuel then acts to move the piston 22, thereby altering the injection timing, until a further position of equilibrium is established. The reaction on the cam 10 of the plunger rollers 9 tending to retard the injection timing is resisted due to the restricted flow in the groove 29.
